Pookie and Louisa Burch created Trademark to fill a void in the market: They couldn't find anything reasonably priced that wasn't too trendy. "I'm 31, and Louisa is in her twenties," says Pookie. "We targeted the price point we could afford"—but at a sensibility that would appeal to women of all ages. "We're obsessed with the idea of building a personal uniform," she says.

right) with stylist and friend Kate Young. They're known for nerdy-chic twists on preppy staples All clothing, Trademark.

On not naming the line after themselves:

"We loved the idea of this one word that would sum something up," says Pookie. "We wanted uniform initially, but we couldn't get it. We tried trademarking all these different words, and someone was like, What about the name Trademark?' It's the perfect word, like your own trademark style."

On why they launched their label:

"We were having a hard time finding clothes that felt classic, beautiful, and well-designed within the price point we could afford," says Pookie. Adds Louisa: "There's this misconception that somehow a contemporary' price point means youth. I remember our mom getting frustrated because designer is so expensive, but then contemporary, where she could afford it, felt so young."

On their mantra:

"Less is more," says Pookie. "It's a very Trademark thing to be a little sparse. I'm getting to a place where I really want to own ten items."

On being brand ambassadors:

"For us, Trademark was always a brand that was supposed to speak to everyone, isolated from who was behind it," says Pookie. "I work in the store a lot," adds Louisa, "and when someone asks about the brand, I'm hesitant to be like, Oh, it's actually me and my sister.' I usually just say it's two young girls."

On their muses:

"[Stylist] Kate Young is a great example of a Trademark woman," says Louisa. "She has a strong point of view, but it's not too glossed over or perfect." Adds Pookie: "Jane Goodall, Christiane Amanpour, Alice Waters, Diane Keaton. Most of the women I love are over fifty."

On the entrepreneurial bug:

"When we were kids, we cleaned out our closet and did a charity sale in our house in Philadelphia," says Louisa. "We merchandised our clothing, and it was how we mixed it all together that really got people. We raised $3,500."

On the best career advice they've received:

"Tory [Burch, their stepmother] always said never to let anything negative get to you; stay focused and believe in yourself," says Louisa. "People love to throw their opinions around, and it can be a lot of noise." Adds Pookie: "She and our mother are two women we really admire." Says Louisa: "It's interesting because I'll hear Tory on conference calls, and she is still a part of even the small things. I'm like, You're still dealing with that?'"
